Kiner hit 369 home runs during his 10-year career, mostly with the Pittsburgh Pirates. He won or tied for the National League lead in homers in each of his first seven seasons.

Despite a bout with Bell's palsy, which left him with slightly slurred speech, Kiner continued broadcasting for 53 seasons.

According to the Hall of Fame, Kiner's Mets' broadcasting career was the third-longest for an active broadcaster with a single team, with only Los Angeles Dodgers announcers Vin Scully (1950–present) and Jaime Jarrín (1959–present) having more time in the booth.

His traditional home run call -- "It is gone, goodbye" or "That ball is gone, goodbye" -- was a signature phrase in baseball.
